Description

Anti-collision device for flat-headed automobiles

technical field

The utility model relates to the field of vehicle passive safety, in particular to a collision protection device for flat-headed automobiles. the

Background technique

A flat-top car, that is, a vehicle whose engine is arranged in the cab of the car. According to statistics, in the traffic accidents of casualties of drivers and passengers, the proportion of flat-top cars is the highest among all types of vehicles. Due to its own structural characteristics, once a collision accident occurs, the body of the flat-top car will be seriously deformed. In addition, the distance between the driver and the front end of the vehicle is very short, and the body lacks cushioning when the body deforms. Therefore, the deformation of the body will cause serious crushing injuries to the occupants. Cause serious accident consequences and casualties. the

At present, the safety of flat-top cars has received extensive attention. Since 2005, the state has banned the production of small passenger cars. For large flat-headed cars, there are two main types of safety devices generally used at present: protective frames and safety airbags. The protective frame is a cantilever structure installed at the front end of the car. It is welded by steel plates and has a small force-bearing area. When a collision occurs, it not only cannot play a good protective role, but sometimes it will aggravate the damage of the car body. For airbags , due to the limitation of the structure characteristics of flat-top vehicles, the airbag does not have enough time to open during the vehicle collision deformation process, so the protective effect is not obvious. the

In the event of frontal and side collisions, the buffer springs and anti-collision steel beams in the collision buffer module will also deform to absorb part of the collision energy. The energy absorber is the second collision buffer energy-absorbing device, which absorbs the collision energy by the internal damping material through telescopic deformation. During the collision process, part of the collision force will be transmitted to the support seat through the force-bearing holder installed at the rear end of the energy absorber, and the support seat can absorb part of the collision energy through deformation. When a collision occurs, through the collision buffer module-energy absorber-support seat, three energy-absorbing buffer processes are formed. Energy-absorbing cushioning. In this way, five energy-absorbing buffering processes of buffer steel plate-buffer spring-anti-collision steel beam-energy absorber-support seat are actually formed, thereby effectively reducing the collision energy acting on the vehicle body, reducing the deformation of the vehicle body, and effectively The personal safety of the occupants in the vehicle is protected when a collision occurs. the
